USES: This product is used to treat stomach/intestinal ulcers caused by the bacteria H. pylori and to prevent the ulcers from returning. Treating an ulcer reduces the risk of serious damage to the lining of the stomach/intestines (such as bleeding, tearing, blockage).Lansoprazole is known as a proton pump inhibitor (PPI). It works by blocking acid production in the stomach. Decreasing excess stomach acid can help the ulcer heal. Amoxicillin and clarithromycin are antibiotics used to treat a wide variety of bacterial infections (including H. pylori). Treating the infection helps reduce the risk of the ulcer returning. Amoxicillin is a penicillin-type antibiotic and clarithromycin is a macrolide-type antibiotic. They work by stopping the growth of bacteria.The antibiotics in this product treat only bacterial infections. Antibiotics do not work for viral infections (such as common cold, flu). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.
